This invention relates to improvements in caps for bottles and has for itsobject to provide a cap for bottleswhich may be easily and cheaply constructed, easily appliedfto the neck of the bottle and which providesan adequate-protection against refilling when the bottle has been once emptied. It is often the case that where a manufacturer has put' u on the market certain goods exceedingly ne in quality and has built upi'a large business in that commodity, imitations appear {in the market which pass off goods of grea the public in containers and under trade names exactly similar to those used by the original manufacturer. This is particularl true in the case of liquids put.up in bot es, as for instance hair tonics, toilet waters, perfume and other liqu'ids, as the empty bottles are easy to rocure.

and easily refilled with an interior su stitute, especially where the hair tonic or the like is dispensed in barber shops, beauty parlors and the like, greatly to the damage of'the original manufacturer whose sales are thus interfered with and whose reputation as to the quality of his products is impaired.

It is one of the objects of this invention therefore to provide. a cap for bottles such as hair tonic, toilet water, perfume or other bottles which'will make it impossible to re.- fill the bottle.

Another object of the invention is to r0- vide a non-refillable cap for bottles w ich will resist bur larizing and revent opening 0}? the non-refillable caps wit out destroying t e ca Another object of the invention is to tovide a non-refillable cap for a. bottle w i'ch contains a float to adequately seal the mouth of the bottle if it is attempted to force or draw liquid into the bottle when the bottle is in an inverted position.

These objects as well as others which will appear as the. description of the invention proceeds, I propose to accomplish while keeping the cost of, the non-refillable ca at a minimum, and well within the economic limit which manufacturers of valuable 'liquids can ay.

Referring now to the drawings.

vIn the form of embodiment of the inven-- tion illustrated, a cap 10 is mounted over the mouth of any suitable bottle 11, havinlg the usual beaded or enlarged rim 12, a jacent the mouth thereof. A tubular outer casing or shell 13, of the cap 10 is constructed of relativel hard metal such as brass, nickel or the ike and is adapted to be slipped over the mouth and} enlarged rim 12, of the bottle 11, in such a manner thatv edge 14 of the shell 13 comes below themlarged rim 12 and may be crimped or turned inwardly thereby grasping the neck of the bottle below the rim 12 and holding the cap 10 tightly and permanently on the top I of the bottle 11.

A dispensing spout or nozzle 15 at the top of and integral with the cap 10, is

threaded to receive a covercap 16, .havmg a resilient stopper 17 to close and seal the top of the nozzle 15 when the sealing cap 16 isfscrewedinto place.

The arrangement thus ar described is the more or less common t of cap for hair tonic and other bottles ith the exception that my cap is made of harder metal to prevent its removal when once installed on the bottle.-

The part to prevent refilling of the bottle comprises a cup. 18 havm a cylindrical well 19- adapted to fiteasi y into the mouth of the bottle, 11, and a. flange 2O ada ted to rest upon the top of the mouth of the bottle and support the cu 18 therein. The cup 18 has a hole 21 in the bot- I the bottle may gether as a unit tom thereof to permit the liquid in the bottle to run out through the nozzle when the bottle is inverted. A ring or washer 22 of compressible material such as cork is preferably disposed between the flange 20 of the cup 18 and the top of the mouth of the bottle 11 and adequately prevents any of the liquid from leaking therebetween. The washer 22 is made preferably of such a diameter that it will fit snugly between the shell 13 and the walls of the cu 18 to hold the cap frictionally in the 'shel 13, so that the cap and the parts to prevent refilling of be assembled and held tofor convenient securing of the same to the bottle mouth.

A valve or float 23 made preferably of cork or other light material and'of a diameter a little less than the inside diameter of the well 19 of the cup 18, is disposed within the well 19 and is free to move longitudinally thereof, and normally covers the hole 21 in the cup 18 when the bottle is in upright position. This valve 23 has a plurality of notches 24 in its periphery adapted to permit liquid from the bottle to flow past the valve when the bottle is inverted.

A protecting disc 25 substantially cylindrical in shape, made preferably of steel and case hardened is carried in the well 19. This disc has a plurality of grooves 26 extendin along the sides parallel to the axis thereo and other grooves 27 on the upper end thereof connecting the upper ends of the grooves 26, on the sides. The disc 25.

is of a diameter to fit easily within the well 19 of the on 18, and its length is such that when place within said cup 18 above the cork valve 23 there is a space 28, permitting the reci rocation of the valve 23 and disc 25 withm the well 19 of the cup 18.

. narily the bottle is The operation of the devices is as follows: When it is desired to obtain some of the liquid from the bottle 11, the same is inverted as is done with an ordinary bottle having a simple spout or nozzle cap. The

disc 25 slides toward the nozzle until it,

strikes against the upper inside surface of the shell 13 at the base of the spout or nozzle 15. This allows the liquid in the bottle to ass through the hole 21 in the cup 18 an push the float 23, if it has not already been moved, by gravity, against the disc 25. The liquid then passes through the notches 24 in the float 23, through the grooves 26 in the disc 25 and across the top of the disc through the grooves 27 and drips or runs from the spout or nozzle 15. Ordigiven a shaking motion to apply the liquid, drop by drop to the scalp or the like.

When the bottle is righted, the disc 25 slides back to its normal position at the bottom of the well 19, pushing the valve 23 before it so that the valve covers the hole 21 in the cup 18 and acts asa seal to prevent evaporation if it is desired not to replace the cover cap 16.

The bottle and cap as described is thus completely non-refillable. Due to the use of hard metal in the shell 13, the cap cannot be removed and replaced upon the bottle without the use of very expensive machinery. The bottle cannot be refilled when in inverted position because the float 23 will rise with the li uid and close the port 21 before any liqui enters'the bottle, and the bottle cannot be burglarized by drillin through disc 25 with a drill projecte through the hole 15 because the hardened face of the disc and the configuration of the grooves 27 will prevent penetration by the drill and will cause the disc to catchon the facets of the drill and turn therewith in the well 19.

As will be noted from the foregoing description the parts comprising the invention are simple and easily and cheaply made, all can be made with automatic machinery with small cost for materials or labor: the parts are easily assembled, and the assembled cap 13 and cup 18 are held together before applying to a bottle by the snugly fitting compressible ring or washer 22. The invention therefore represents a highly efficient, inexpensive and absolutely non-refillable cap for bottles and inasmuch as many variations and changes of the embodiment of the invention may be resorted to Without departing from the spirit of the invention, I do not wish to limit the invention, to the specific embodiment shown but to interpret it as broadly as the scope of the appended claims will permit.
